Showroom Product Company Profile

Desription:
Pneumatic Diaphragm Valve (CV3000) is composed by springs controllers and low-flow female seats. The new developed controller is light in weight and much lower in height, and is convinient to take with. This controller has relatively high flow capacity. It has other characteristics: Stablly working, consistence and flow control precision and widely adjustbale range. All the mentioned performance features of such controller valves can win its name on good controlling capacity.

Remarks:
Pneumatic Diaphragm Valve (CV3000)
1P stands for valves positioner; R— Pressure servomotor.
2The allowable pressure deviation is P2=0: The valve is on turning off situation, P reaches the highest level.
3If the maximum pressure is more than 1.0Mpa, we advice to weld hard or other suitable materials as the tapon and seat surface.
Enclosed sectors
Positioner, Gear Box, air filter and pressure reducers
